Is there something like tab functionality in the Pre browser? When logging into these forums, I want to be able to tab from my username to the password field. Someone said it was "the arrow key" and then "enter" in the Pre tricks and tips forum, but not only is "the arrow key" vague (there are 3 arrows on the keyboard) but so were the instructions (do you press and hold, press each key in sequence, press both at the same time...?) Anyway, I haven't had any luck in the browser.
